Use stringr functions for consistent and readable string operations
* * *
Utilize stringr package functions for cleaner string manipulation in R
* * *
The following code demonstrates the use of stringr functions to perform string operations in a more readable and consistent manner:
< Good Code >
Load the stringr package
library(stringr)
Example string
text <- "Hello, World! How are you?"
Using stringr functions for string operations
1. Extract substring
substring <- str_sub(text, start = 1, end = 5)
2. Convert to uppercase
uppercase <- str_to_upper(text)
3. Count occurrences of a pattern
count <- str_count(text, pattern = "o")
4. Replace pattern
eplaced <- str_replace_all(text, pattern = "o", replacement = "0")
5. Split string
split_text <- str_split(text, pattern = " ")
